Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as pure pentafluoroethane (HFC-125) without blending
Pure halogenated hydrocarbons fall under Chapter 29 as individual chemical compounds rather than mixtures.
If contains ozone-depleting substances like HCFCs above trace levels
Mixtures with CFCs, HCFCs or specific hazardous substances are classified under 3824 for environmental control.
If when pre-charged in refrigeration equipment components
Refrigerant gas contained within assembled heat exchange units moves to Chapter 84 machinery classification.

Import Tips & Compliance
• Obtain EPA Significant New Alternatives Policy (SNAP) approval and ensure F-gas import certification
• Provide Safety Data Sheets (SDS) and detailed composition analysis verifying ≥40% HFC-125 content
• Avoid misclassification as pure HFC-125 (2903.39) by documenting exact blend percentages
